LON

Each LON device provides network variables (SNVTs) for communication with other devices. The required variables are selected based on the device documentation or the Xif file (machine-readable representation of all used SNVTs) and entered in the KL6401 via the KS2000. The KS2000 can now be used to create another Xif file. Both Xif files are read and combined with a LON configuration tool (not provided by Beckhoff). For further information please refer to the respective tool.

For each SNVT entered in the KL6401, a suitable function block has to be programmed on the PLC side. These function blocks can then be used to access the SNVTs of the devices.
